Abstract

The Palaearctic species of Eurytoma (Hymenoptera: Eurytomidae) developing in stone fruits (Rosaceae: Prunoideae).

Abstract

Species of the genus Eurytoma associated with stone fruits in the Palaearctic region are discussed. The following 8 species are known to have such an association: E. amygdali, E. maslovskii, E. padi, E. samsonovi, E. schreineri, E. turkestanica sp. nov., E. paramygdali sp. nov. and E. armenica sp. nov. The first 6 species are phytophagous, developing in the stones, and the last 2 are entomophytophages, starting their development as parasitoids of a phytophagous species and completing development feeding on plant tissue. Four species, E. amygdali, E. schreineri, E. samsonovi and E. maslovskii, are of economic importance. Information is given on the economic importance, biology, distribution and taxonomy of these species, and includes several new records for hosts and distribution. The new species are described, and a key is given to all the species.
